Answer:
First option tan x° = 8 ÷6
Step-by-step explanation:
When we solve for angles in a right angled triangle or we are trying to find one if the sides of a right angled triangle, we used trigonometric functions to find our answers. These trigonometric functions include Sine (sin) , Cosine (cos) and Tangent (tan)
Tangent also called short form tan is used when solving problems involving a right angled triangle.
A right angled triangle has 3 sides, the Hypotenuse, the opposite side and the adjacent side.
When we are asked to find the tangent of an angle,
tan = Opposite side / Adjacent side
In the question above, we are asked to find tan x° where x is the angle.
The opposite side = 8cm
The adjacent side = 6cm
Therefore, tan x° = 8cm/6cm = 8cm ÷ 6cm
cosU:-
As U lies in Q3
sinV
As V lies in Q3
So
